6 GENERAL DESCRIPTION:

2,4-D amine is a post emergent, translocated herbicide for the control of broad leaved weeds.

It is mainly absorbed through the foliage with some root uptake. Its low level of volatility


4 of 12 22/02/2014 10:59 AM

makes it safer to use than the ester formulations close to sensitive crops. Low levels of drift

can cause high levels of symptoms on sensitive species.

7 APPLICATION METHODS AND TIPS:

Best results when applied in fine weather to actively growing plants.

8 WEATHER:

Rainfast in 6 hours.

Frost effects: Frost before application may retard weed growth thus reducing translocation.

For best results, 2-3 frost free days required after application.

Wind: Regulations require application when wind speeds are between 3 and 15 km/hour to

reduce the risk of damage caused by drift. Avoid spraying when wind is blowing towards

sensitive crops.

Inversions: Don't apply during inversion conditions as damaging levels of herbicide drift may

move a kilometre or more.

Temperature:

Delta T and Relative Humidity: Avoid application when Delta T is greater than

9 ADJUVANTS:

Generally none are required.

Wetting agents may be useful for hard to wet plants and in non selective situations to improve

droplet retention.

Wetting agents and spray oils may increase the risk of crop damage.

10 WATER QUALITY:

Hard water: There may be a slight loss of activity due to ionic bonding in very hard water.

Salty water: Relatively tolerant of salty water.

Colloids: Some loss of activity as the amount of clay in the water increases. If it is difficult to

see a coin on the bottom of a 10 litre bucket full of water then the water should be cleared or

an alternate source found.

pH: Acidic water is usually OK. Highly alkaline water may cause loss of efficacy.

11 COMPATIBILITY:

Trace elements.

Do NOT mix with :- Trace element fertilisers, glyphosate 360 and CT

Zinc sulphate and copper sulphate are antagonistic with 2,4-D amine. This is caused by ionic

reactions and results in a significant loss of efficacy. Manganese sulphate and calcium

carbonate (lime) have lesser effects.

See HerbiGuide Compatibilities button.

12 EQUIPMENT:

Boom sprays, aircraft, high and low volume hand leads, misters.

Regulations require the use of coarse droplets to reduce the impacts of drift.

Recommended water volume: 30 - 120 L/ha for boom sprays, 10 - 90 L/ha aircraft and 200 -


5 of 12 22/02/2014 10:59 AM

1000 L/ha for hand leads.

Nozzle type: Flat fan at pressures of 200 - 300 kPa (28.6 - 43.5 psi).

13 SPRAYER DECONTAMINATION:

Clean Up:

Remove filters and nozzles and manually clean separately. Rinse with soapy water or water

plus wetting agent and run through boom. Rinse with water.

Decontamination:

Remove filters and nozzles and manually clean then soak in 500 mL household ammonia in

10 L water for 30 minutes.

Rinse sprayer with soapy water (eg 500 mL or g of Drive, Dynamo, Omo or Surf per 100 L

water) or water plus 0.25% wetting agent and run through boom. Fill with 1% solution of

ammonia and allow to stand for several hours. Triple rinse with water. Or use a commercial

spray tank and equipment cleaner.

Rinse nozzles and filters in water and replace.

14 HERBICIDE RESISTANCE:

Some plants have developed some resistance to 2,4-D.

15 REPLANTING INTERVALS:

Crop Time

Barley 13-14 days in moist soil. 21 days if dry. Qld 0 days

Cereal Rye 13-14 days in moist soil. 21 days if dry. Qld 0 days

Chickpea 14 days in dry soil.

Field Pea 7 days in moist soil. Longer if dry.

Lupin 7 days in moist soil. Longer if dry.

Pasture 14 days in moist soil. 21 days if dry.

Triticale 13-14 days in moist soil. 21 days if dry. Qld 0 days

Wheat 13-14 days in moist soil. 21 days if dry. Qld 0 days

16 WITHHOLDING PERIODS:

Crop Type Time

All Harvest Not required

All Grazing 7 days

17 RE-ENTRY PERIOD:

Wear protective clothing if working in crops before the spray has dried.

18 PROTECTIVE CLOTHING:


6 of 12 22/02/2014 10:59 AM

Face shield, cotton overalls, gloves, boots.

19 SOIL:

Soil type has little direct effect.

20 MODE OF ACTION:

Foliar absorbed with some root absorption, translocated, post-emergent.

Disrupts cell growth and elongation. Multiple sites of action.

Uptake and translocation:

High concentrations may cause leaf burn and poor translocation leading to poor weed control.

Translocated both up and down from the site of application to sources of active growth.

Physiological effects:

Causes twisting, swelling and splitting of soft stems and abnormal growth of leaves often

resulting in cupping and inter veinal chlorosis. Flowers are often deformed and seed viability

may be affected. These symptoms may occur at very low dose rates.

Residual Life and Breakdown:

21 SELECTIVITY:

Most grasses are tolerant to 2,4-D. Woody plants have lower tolerances and soft broad leaved

species are generally susceptible to rates around 1 kg a.e./ha.

Crop effects are usually only noticeable if applied at the incorrect growth stage and/or

excessive rates.

Plant roots absorb polar (salt and amine) forms of 2,4-D most readily and leaves absorb non

polar (ester) forms most readily. Salt formulations have negligible vapour pressure are the

safer to use in close proximity to sensitive plants whereas ester formulations are generally

safer prior to planting susceptible crops.

Crop tolerance:

Varietal sensitivities:

Applying 2,4-D to wheat before the completion of ear development may lead to yield loss and

head deformities. Some varieties complete ear development at an earlier growth stage than

others. The earliest timing for 2,4-D application therefore depends on the variety as indicated

below

Effect on Clover Species:

Research done by Nufarm shows that clover tolerance increases at later growth stages and that

at 1.4 L/ha minimal to light but acceptable damage to Balansa cv Paradana and subterranean

clover cv Mt Barker, Trikkala, Larissa, Woogenellup and Northam occurs. Generally not as

safe as MCPA 250 and 500 except on white clover. Few weed control advantages so MCPA is

preferred.

Effect on Medic Species:

Damage trials as carried out by Nufarm.

Low rates of 350 ml/ha for barrel medic cv Parragio, Sephi, Cyprus and Parabinga; gamma

medic cv Paraponto; snail medic cv sava; spineless burr medic cv Circle Valley and Serena

and strand medic cv Harbinger cause minimal to light but acceptable damage. Higher rates

cause unacceptable damage.


8 of 12 22/02/2014 10:59 AM

Effect on Lucerne:

Death of seedlings or established plants very common especially at low rates of herbicides

and even if leaf growth is at a minimum when sprayed. All formulations can cause severe

damage, cutting/grazing prior to spraying can reduce damage but damage is usually

unacceptable and severe. Herbicide drift onto lucerne can cause damage.

Effect on Native Plants:

Most native plants will tolerate low levels of 2,4-D and drift is not expected to cause

significant long term effects on roadside trees or vegetation if reasonable care is taken to

avoid exposure.

22 DISEASE AND INSECT EFFECTS:

Vascular diseases usually reduce the translocation of 2,4-D and may reduce efficacy. Leaf

diseases may reduce the leaf area available for 2,4-D absorption and consequently reduce

efficacy.

Low levels of insect damage may increase the absorption of 2,4-D increasing efficacy but also

increasing the risk of crop damage. High levels of defoliation by insects may reduce efficacy

due to decreased leaf area to collect spray droplets compared to the size of the plant.

23 PLANT SYMPTOMS:

Initial symptoms are usually apparent in 3-7 days and include twisting of soft stems, cupping

of leaves and erection of rosette leaves. Malformed growth may take weeks to develop. Death

of young plants usually occurs within a month. Older and more woody plants may take

several months to die.

Table adapted from EPA 738-R-05-002, June 2005

For sensitive species like Tomato, rates around 5 mL/ha of 2,4-D amine can cause symptoms.

For cereals the ester formulations are less damaging to the crop pre planting than the amine

formulations.

SECONDARY EFFECTS:

Sugar contents of sprayed plants normally increase within a week of spraying and this may

make the plants more palatable to herbivores including sheep and insects. This may cause

stock problems if toxic plants are present.

24 TOXICITY:

Summary:

2,4-D amine is generally of low toxicity to mammals, birds, bees and aquatic organisms.

Details:

Poison schedule: S5.

Mammalian toxicity: Low toxicity.

Acute oral: LD50 735-1646 mg/kg (rats) [For comparison table salt is 3000 mg/kg]

Acute dermal: LD50 1829 to >2000 mg/kg (rabbits)

Skin: Primary irritation. Slight skin irritant.

Skin: Sensitisation. Not a dermal sensitizer.

Eye: Severe eye irritant.

Vapour inhalation: LC50 3.1 to >4.97 mg/L (rat)

Chronic oral toxicity: NOEL 5 mg/kg/day for two years rats and 30 mg/kg/day for rabbits.

Acute dietary toxicity: NOEL 25-67 mg/kg/day.

High doses have caused reproductive effects in test animals.

Data indicates that 2,4-D has low teratogenic potential or is not teratogenic.

Several studies investigated 2,4-D as a carcinogen with varying results. At normal exposure

levels it is not expected to be carcinogenic.

Acceptable Daily Intake (ADI): 0.01 mg/kg/day.

Other Species:

Birds: LD50 = 415 to >1000 mg a.e./kg. Moderately to practically non toxic. The acid, amine

and ester formulations have similar toxicity. Chronic NOEC for birds is 992 ppm for 2,4-D

acid formulation.

Fish: toxicity LC50 >80.24 to 2244 mg a.e./L for acid and amine formulations

NOEC of 14.2 to 63.4 mg a.e./L for 2,4-D acid, 2,4-D DEA and 2,4-D DMAS formulations

based on larval fish survival for the fish full life cycle studies.

2,4-D amine and acid formulations are practically non toxic to freshwater and marine fish.

2,4-D acid and dimethyl amine are practically non toxic to tadpoles.

Invertebrates: LC 50 = 25 to 830 mg a.e./L for freshwater and marine invertebrates for 2,4-D

acid and amine formulations. That is slightly toxic to practically non-toxic to freshwater

marine invertebrates.

Bees: Practically non toxic. LD > 10 ug/bee. Moderate doses have impaired brood production.

Arthropods: toxicity.

Earthworms:

25 TOXICITY SYMPTOMS:

26 FIRST AID:

If SWALLOWED: If more than 15 minutes from a hospital, induce vomiting preferably using

Ipecac Syrup APF. See a doctor.

If in EYES: Irrigate with plenty of water. Amine and salt formulations are severe eye irritants.

See a doctor.


10 of 12 22/02/2014 10:59 AM

If on SKIN: Rinse with plenty of water, remove contaminated clothing, wash with soap and

water.

If INHALED: Remove patient to fresh air. See a doctor.

Advice to doctor: Treat symptomatically.

Contact the Poisons Information Centre on 131126.

27 ENVIRONMENTAL FATE:

Half life in soil: 2,4-D acid has a aerobic soil half life of 6.2 days.

Half life in water: 2,4-D acid has an aerobic half life of 15 days and an anaerobic half life of

41-333 days.

2,4-D acid is stable to abiotic hydrolysis with a half life of 1-2 years.

It has an EPA classification for soil mobility that ranges from intermediate to very mobile.

Usually very low mobility in field studies even though laboratory solubility studies indicate

2,4-D is potentially mobile. Rapid degradation in the soil and removal from soil by plant

uptake minimizes leaching under realistic application conditions.

Significant ground water contamination not likely but it has been detected in ground and

surface waters in the US and Canada. Rarely detected more than 500 mm deep in soils.

Accumulation in milk and tissues.

pH stability:

Photolysis rate: 2,4-D acid half life (DT50) was 12.9 days in water at pH 5 and 68 days in

soil.

Hydrolysis half life: Stable to abiotic hydrolysis.

Biodegradation rate: 2,4-D acid half life is 6.9 days in aerobic soils and 15 days in aerobic

aquatic environments. 2,4-D amine and salt formulations are similar. Most field studies show

an apparent half life of 1.7 - 13 days with an average of 5 days in moist soils. In dry soils the

half life is much longer because most of the breakdown is due to microbial activity. The half

life in grass and thatch was < 7 days on average. The half life in natural water is 1-2 weeks

but may be only a few days in rice paddies.

2,4-D degrades through several low toxicity intermediates to carbon compounds, CO2, water

and chlorine or HCl.

UV breakdown rate: Probably has a half life of 2-13 days
